Each and every drummer will eventually change the setup of his/her drum set stands or rack. Be it to try new ideas or to integrate new instruments into the set. Good hardware makes this light work being sturdy, flexible to assemble and expandable as a system. A huge advantage is modular hardware, meaning you can take the pieces apart and put them together in another way.
Many manufactures build modular and a part you buy some years down the line fits with what you have already.
